README for Modified McGuire2014 alignment and NEXUS fileThe McGuire NEXUS file (https://orcid.org/0000-0002-9562-5585) contains sequences for six genes (ND2, AK1, BFIB, ND4, ODC, and MUSK) for a total of 436 hummingbird specimens, representing 284 species. However, some species are represented by more than one specimen. For example: Aglaeactis castelnaudii is represented by the sequence labeled Aglaeactis_castelnaudii but also by Aglaeact_castel_nk159780. We modified the original taxon labeling by McGuire to make our subsequent analyses easier�one exemplar per species was labeled with the full species name that precisely matches the names in our data set (e.g., Aglaeactis_castelnaudii); any additional specimens of the same species were left with their original labeling from McGuire et al. 2014 (e.g., Aglaeact_castel_nk159780), which ensured that they did not match our labeling and were thus easy to exclude in R.Data for the 220 species of our own full dataset encompassed 12 species not included in the McGuire phylogeny. Using the method of Rangel et al. (2015), we placed these �phylogenetically uncertain taxa� (PUTs), at random within the �most derived consensus clade� (MDCC) that unequivocally contains each PUT, without creating polytomies, independently, in each of the 100 alternative phylogenies used to generate the distribution of PGLS residuals for each morphological variable and for each statistical analysis. These 12 species and the literature authorities for assigning each to its MDCC appear in Table B1.Rangel, T. F., R. K. Colwell, G. R. Graves, K. Fu?�kov�, C. Rahbek, and J. A. F. Diniz?Filho. 2015.
